HOSE-COUPLING.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application August 22, Seria/1 N0.

To all whom t may concern:

Be it known that we, RICHARD TooLE and JOHN J. MCDONNELL, citizens of the United States of America, residing at Portage, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

l This invention relates to certain new and useful improvements in hose-couplings; and the invention has for its object the provision of novel means to secure the confronting ends of two sections of hose together without the use of screw-threads.

Another object of this invention is to provide a coupling for hose which can be easily and quickly manipulated to join two sections of hose together. To this end we have devised a novel form of construction wherein positive and reliable means are employed for locking the confronting ends of two sections of hose together, whereby a non-lealiable connection will be established.

Vith the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described and then specifically pointed out in the claims.

Referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which- Figure 1 is a side elevation of our improved coupling. Fig. 2 is an end view of the same. Fig. 3 is a longitudinal vertical sectional view of our improved coupling. Fig. 4 is a cross-sectional view taken on the line a; of Fig. 3. Fig. 5 is a longitudinal sectional view of one of the members of the coupling. Fig. 6 is a cross-sectional view taken on the line 'y 'y of Fig. 5. Fig. 7 is a longitudinal sectional view of the other member of our improved coupling, and Fig. S is a plan of the same.

To put our invention into practice, we employ two tubular members 1 and 2, which constitute the coupling, and to the outer ends of these members we secure the sections of hose which are to be coupled together. We do not care to confine ourselves to the manner of securing the hose to the members, as conventional means may be readily employed. Our invention resides in the manner of securing the members 1 and 2 together, and by referring to Figs. 3 and 5 of the drawings it will be observed that the member' 1 is provided with a cone-shaped enlargement 3, and surrounding this enlargement is a cone-shaped cup 4, the smaller end 5 of which engages a tubular member 1 and abuts against the resilient washer 6, which bears against the shoulder 7 of the coneshaped enlargement 3. The enlarged end of the cone-shaped cup 4 is provided with an annular inwardly-extending flange 8, which will be presently described. Reference will now be had to Figs. 7 and S of the drawings, wherein we have illustrated the construction of the tubular member 2. The tubular member adjacent to its ends is provided with a peripheral collar 9, and carried by this collar is a cone-shaped cup 10, the interior or recessed portion 1 1 of which tapers correspondingly to the cone-shaped enlargement 3 of the member 1. Surrounding the end 12 of the tubular member 2, which extends into the interior or recessed portion of the cup 10, is a resilient washer or gasket 14, which is adapted to rest against the end of the coneshaped enlargement 3 when the members are secured together. The cone-shaped cup 10 is provided with `diametrically-opposed recesses 15 15, and in each one of these recesses is pivotally mounted a lever 16, carrying a handle 17. These levers are normally forced upwardly by springs 18 18, secured within the recesses 15 15, and bear against the underneath surfaces of the levers 16 16.

In Fig. 3 of the drawings we have illustrated the two members coupled together, and by referring to said figure it will be seen that as the member 2 enters the cone-shaped cup 4 of the member 1 the levers 16 are depressed until the cone-shaped cup 10 has passed a suflicient distance within the cone-shaped cup 4 to permit of the shoulders 17 of the levers engaging behind the flange S of the member 1. The two members will be firmly held together until it is desired to separate the same, at which time it is only necessary to press the ends of the levers 16 16 together and remove the shoulders 17 from the flange 8 of the member 1, at which time the member 2 .can be withdrawn from the member 1.

The construction of the cone-shaped ends and cups of the members provides an interlocking coupling, and the manner in which the tubular portions of these members over- IOO IIO

lie `one another provides a non-leakable and positive connection between the sections of hose secured to said members. It will also be observed that the construction of o ur improved coupling is extremely simple. Therefore it can be manufactured at a comparatively small expense. We preferably con-` struct the coupling of bronze or any suitable material which will provide a strong and durable coupling capable of withstanding the rough usage to which couplings of firehose are subjected,

lt is thought from the foregoing that the construction, operation, and advantages of the herein-described hose-coupling will be apparent without further description, and various changes in the form, proportion7 and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Vhat we claim, and desire to secure by Letters Patent, is-

l. In a hose-coupling, the combination of a tubular member having a cone-shaped enlargement, a cone-shaped cup carried by said member, another member adapted to be connected to said member, a cone-shaped cup carried by said member and adapted to fit within the rst-named cup, said cup having recesses formed therein, spring-pressed levers mounted in said recesses and adapted to engage in the first-named cup, resilient gaskets mounted between said members, substantially as described.

2. A hose-coupling consisting of two members, one adapted to t within the other, a cone-shaped enlargement carried by one of said members, a cone-shaped cup carried by said member, a cone-shaped cup carried by the other of said members, said member having recesses formed therein, and means to detachably secure the last-named member within the irst-named member, substantially as described.

In testimony whereof we afliX our signatures in the presence of two witnesses.
